Method of producing organ model, mold for producing organ model, and organ model

Abstract

The present invention provides a method of producing an organ model comprising; an outer-shape body forming step in which an outer-shape body 120 having regions 16, 17 to be a hollow portion and a structural wall of the organ model respectively is formed by irradiating curing light and cure the photocurable mold resin 12 and support resin 13 supporting the mold resin based on photographed data of a human organ, a mold shell forming step in which a mold shell 10 having outer and inner shell portions 12A, 12B covering outer and inner surfaces of the organ model respectively is formed by removing the support resin 13 from the outer-shape body 120, a filling step in which a space 15 between the outer and inner shell portions 12A, 12B is filled with a flexible injection molding material 20, and a removing step for removing the mold shell 10.

Description

TECHNICAL FIELD[0001]The present invention relates to a method for producing an organ model (phantom) which is a stereo model of various organs existing inside a living body such as a human body, a mold for producing the organ model used in such a method, and the organ model which is produced using the method and / or the mold.BACKGROUND ART[0002]Conventionally, an X-ray apparatus, a CT scanning apparatus, an ultrasonic diagnostic apparatus, or the like is used in medical sites. A doctor understands the state of a lesion from data (2-dimensional data such as a photograph and image data) obtained from such apparatuses, or performs actual operations referring to such data. On performing an actual operation on a human body, it is important to understand the target lesion not only by 2-dimensional data such as a photograph but in a 3-dimensional manner. For example, in an operation for treating a heart by a catheter, it is preferable to previously understand the specific structure of the ...

AI Technical Summary

Benefits of technology

The patent presents a way to make a realistic and flexible model of a human organ using a low-cost material. This model can be produced with high accuracy.

Problems solved by technology

However, it is not sufficient since the structure of an organ of a human is different from that of an animal due to the difference of the basic biological structure between the human and the animal.

Further, when such animal is used as an object for the training in which the catheter is operated, the behavior of the catheter in a heart structure of an actual human body cannot visually be understood.

The above-mentioned organ model produced by such rapid prototyping has hardness extremely higher than an actual human organ, and is not flexible as the organ since the organ model is composed of a photocurable resin.

Therefore, the behavior of the catheter during the operation as mentioned above is different, not to mention the difference in the feel of touch, so that such organ model is not suitable for simulating the actual operation.

Further, it is difficult to produce an organ model which provides the feel of touch similar to that of the actual human organ and precisely copies the shape of the actual human organ, easily with low cost.
